SAD-=IRON.

SPECIFICATION forming part of Letters Patent No. 383,319, dated May 22,1888.

Application filed June 29, 1887. Serial No. 212,852. (No lllOilBl.)

To all whom, it may concern:

Be it known that I, THOMAS H. PATTERSON, a citizen ofthe United States,residing at East Saginaw, in the county of Saginaw and State ofMichigan, have invented certain new and useful Improvements inSad-lrons; and I do declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, and to the letters and figures ofreference marked thereon, which form a part of this specification.

This invention relates to that class of sad irons known as double-facedor revolving irons. The face of theidle side ofthe iron is heated by theflames from a burner which is fed from a vessel containing fluid or oil,and is revolved or turned under as a hot ironingsurface is required, asis the common practice.

The special features of this invention consist in the peculiarconstruction of the reservoir,

the manner of attaching it to thciron, and the special devices forcontrolling the flow of the uid.

In the accompanying drawings, forming a part of the specification,Figure 1 is a perspective of my improved device. Fig. 2 is a verticalcentral section of the vessel and joining parts, taken on the dottedline 00 00 of Fig. 1. Fig. 3 is a longitudinal section of Fig. 1, takenon the dotted line H. Figs. 4 and 5 are enlarged details, as will behereinafter set forth.

In the drawings, F represents the sad-iron, having the ironing-faces orsurface-plates O O, the edges of which are provided with a series ofvent-holes, e, or hot-air passages.

The central or body iron, H, is provided with a series of inducts orair-feeding holes, at. Through said holes the air enters in feeding theflames of the burner J, located in the hollow of the centraliron, H.(See Fig. 3.) The central iron is provided with journals R R at theends. Saidjournals turn in the lower ends of the handle-arms A A. Theupper ends of said arms are attached to the hollow handle N by means ofthe rod or bolt 3 (See Figs. 1 and 8.

L is a lever which is pivoted to the lugs d on one of the arms A, havingon its back face a spring, V, whereby the lower end of the lever isforced into the slotted journal R, as shown in Fig. 1. Pressing saidlever L toward the arm A causes the lower end of said lever to draw outof the channel 12 of thejournal B,

when the iron F maybeiurned or revolved and locked in position by thelever L, as shown in Figs. 1 and 3.

The burner consists of the head 'D, having the central conical dischargeport, and series of projecting blades 7, having spaces 8 be tween them,and cap 0, having the closed head 9, which is made to snugly slide overthe blades 7, as shown in Fig.

W is a feed-pipe screw-threaded to the head D, and passes freely throughthe hollow journal R at 16. (See Fig. 3.) Attached to the other end ofthe pipe \V is a three-way coupling-head, at, having the cap orstuffing-box 3, to which is screw-threaded the rod 4, having thethumb-button i. The opposite end ofsaid rod is pointed or conical, asshown at 5. (See Fig. 3.) By turning the thumb'button t the conical endof the rod 4 is projected into and drawn from the conical port 6, toincrease and decrease the flow of fluid into the burner. Thecoupling-head m is provided with a diaphragm, h, having adischarge-port, e.

B is the vessel or tank for the tluid, and has a hollow standard, 15,coupled to the head m, forming a passage for the fluid to the head at.

f is a nonconducting substance (preferably asbestus) which encircles thestandard 15, and D is a perforatedjacket or gauze-wire coveringsurrounding the asbestus, as clearly shown in Figs. 2 and 3.

Passing through the vessel B and screwthreaded t0 the cap 0 thereof is arod, 01., having at one end the thumb-button i; at the other end theconical point a. Said point is pro jected into and drawn from thedischargeport e,'for the purpose of regulating and to cut off the flowof oil into the coupling-head at.

SS represent curved springs, which are made fast to one of the arms Aand so shaped as to receive and firmly grasp the covered standard 15,holding the vessel B in an upright position, thereby securing the vesseland its burner in position on the iron.

P is a relief-pipe, one end of which has commnnication with thecouplinghead, the other with the vessel B, as clearly shown in Figs. 1and 2.

Z is a filling-cap located in the top of the ves sel. By its removal thevessel may be charged with oil or fluid, and when the iron is in usesaid cap must be kept closed tight to prevent the escape of the fluid atsaid point.

The operations are as follows: To allow the fluid to pass from thevessel B into the coupling-head in, the thumb-button t is turned so asto draw the point a of the rod 12 out of the port 6 of the diaphragm h.Then, to start the flow of fluid intothe burner J, the thumb-button t isturned, drawing the conical point 5 of the rod 4 from the conicaldischarge 6 in the head D, the discharge being cut off by turning thethumb-button t in a reverse direction. The heat from the burner and fromthe iron surrounding the iIJflOWPiPBX/V causes said pipe to becomesuflieientlyhot to generate gas therein more rapidly than it can escapeinto the burner. As a relief for said gas the pipe P is coupled to thehead m, leading into the top of the vessel B. Through said pipe thesurplus gas escapes into the vessel, being therein retained, andpreventing explosion of the generatingpipe WV, and allowing a freeinflow of oil to said pipe.

The object of the metal jacket D and nonconducting coveringf around thepipe 15 1s to prevent the heating of said pipe from the iron, thuskeeping the fluid in said pipe cool. The metal jacket D forms a strongand durable cylinder, to be forced between the supportingsprings S,whereby the vessel is held in position.

Having thus set forth my invention, what I claim as new, and desire tosecure by Letters Patent, is-

In combination with the sad-iron, the burner, the vessel, thecoupling-head, the pipes joining said parts, the rod 4, having the thumbbutton 25, the rod n, adapted to close the port 6', the non-conductingmaterial surrounding the pipe 15, with perforated metal jacket D, andsprings S, mounted on the arm A of the handle, as and for the purposesspecified.

In testimony whereof I affix my signature in presence of two witnesses.

THOMAS H. PATTERSON.
